Subject: mtd: nand: docg4: remove unnecessary platform_set_drvdata()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=4fdcd3ff963bb53b141f8c3624cc5e54cacc8937;p=deliverable%2Flinux.git

mtd: nand: docg4: remove unnecessary platform_set_drvdata()

The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound).
Thus, it is not needed to manually clear the device driver data to NULL.
